## Job description

Quantum Space is redefining mobility and maneuverability in space. Our high-mobility spacecraft platforms support national security, civil, and commercial missions with unmatched flexibility and propulsion capability. We build fast and iterate quickly.

Who We’re Looking For

We are seeking a technically driven EGSE/ Avionics Test Software Engineer to develop automated test software, Electrical Ground Support Equipment (EGSE) software, and hardware/software integration test infrastructure for spacecraft avionics supporting Ranger missions.

In this role, you will develop reusable test applications, instrument interfaces, and automated test sequencing capabilities used to verify spacecraft avionics hardware and software. You will work closely with avionics, flight software, electrical, systems, and test engineers to build reliable test infrastructure, troubleshoot complex hardware/software interactions, and ensure test results are accurate, repeatable, and defensible.

This position is ideal for an engineer who enjoys working at the intersection of software and hardware, solving difficult integration problems, and building robust test systems that directly contribute to flight readiness and mission success.
